We love our four inch cooling gel memory foam mattress topper. It does take several hours to reach its full thickness and has straps on each corner to help hold in place. It seems a little firm at first until you body sinks in some.

Very nice mattress topper. It saved us from having to buy another new mattress to replace one that was too firm. This made it much more comfortable. The corner straps don’t work very well, as they slip off the mattress. I ended up tying them to the bed frame to keep it from slipping around. Keep in mind, if you have a thick mattress, your sheets may not fit well.

This a very nice mattress topper. It definitely added comfort to my very firm mattress. I really like the adjustable straps to go i around the corners of the mattress so the topper stays still. The topper material is good quality and even has a “breathable” material underneath. It was packaged nicely and arrived in 2 layers of protective wrap. I simply let the topper “expand” over a short period of time and it is super comfortable!

This is a nice mattress pad! I went from a memory foam mattress from a well-known brand to a pillow-top mattress with this cover. I would say that this feels more or less the same as my previous mattress. It's extremely comfortable! It never completely fluffed up to shape, which is why I deducted a star. A few weeks later, it is still only about 2 inches around some of the corners and edges, but the full four inches elsewhere. You can't tell once the bed its made, though. The other picture shows what it looks like out of the packaging. I waited about 18 hours before sleeping on it. So far it seems to be holding up well, and it gets its shape back within 30 minutes to an hour in the morning.

I cant wait to add this topper to my new mattress. Im still waiting on my mattress delivery (I shouldve ordered that from wayfair too) and I will definitely need someone to help me because this king size is very heavy. There is no odor upon opening like some other toppers have. Ill update as soon as I get my new mattress. Overall I would recommend because of the weight, available sizes, cost and quick shipment.

THE MATTRESS PAD ARRIVED FOLDED IN THE BOX. AS I UNPACKAGED IT THE ELECTRIC SHOCK ACTUALLY HURT. I LAID IT OUT OVERNIGHT. IT FLUFFED UP THE NEXT MORNING. WE USED IT ON MY DAUGHTERS TWIN BED. SHE SAYS ITS COMFORTABLE. SHE SLEPT BETTER. AND ITS GOOD ON HER BACK. HER ONLY COMPLAINT IS THAT IT SHIFTS EVEN WITH THE STRAPS. OVERALL ITS GOOD.

I’m very happy with this mattress topper for a king mattress in a guest room. First, be aware it takes about 24 hours for it to inflate to the 4 inches so just be patient. I like the straps to hold it in place as well. There is a strong chemical smell when it is first unwrapped…but after about 3-4 days it dissipates. This topper is a game changer for an older mattress. It ended up saving us from having to buy a new one. Very happy with this purchase.

This mattress topper is comfortable, cool, and did not have a bad smell when it was opened! Definitely a cheaper way to get a little more life out of an older mattress or to soften up a firm mattress! Comes with a cover!

This is a dense mattress topper. The topper is medium to firm in feel. It comes in a big box and is heavy. It’s a quality mattress topper. I like that it has straps to hold it in place. See picture. It took a bit for it to fill out to the four inches. It smelt like the plastic for awhile. That’s expected I guess. I am happy with my purchase.

Quick delivery and ready to use
